Box 196650 Anchorage, Alaska 99519-6650 Ref: Septic System Upgrade for Lot 1, Heritage Heights Subdivision To whom it may concern: The existing 4 bedroom house is served by a private septic system. The septic system consists of a 1000 gallon septic tank and a pit type drainfield that is failed, and must be upgraded. A test hole was excavated south ofthe existing septic system in the area ofthe proposed upgrade. The new septic system will be designed around the 30 foot radius ofthis test hole. We are proposing that a new 1250 gallon septic tank and 5 feet wide trench type drainfield be installed. Comments regarding the design are summarized as follows: 1. SOILS: See the attached log which shows the soil classifications, groundwater monitoring, and the percolation test results. It is our opinion that due to the overall appearance of the soils, an application rate of 1.2 gallons/day/fl2 should be used. 2. TRENCtl DESIGN: a. Percolation Rate: <1 minutes/inch b. Allowable Application Rate: 1.2 gallons/day/ft2 c. NumberofBedrooms: 4 d. Design Flow: 600 gallons per day e. Minimum Absorption Area: 500 ft2 f. Total Depth: I 1 feet (max.) g. Effective Depth: 4 feet h. Width: 5.0 feet i. Reduction Factor: 0.5 · Minimum Length: 50 feet total len_gth ~. Effective absorption area = 500 R2 3. SURFACE WATERS: There are no surface waters within 100 feet of the proposed upgrade. 6901 Debarr Road, Suite 2B * Anchorage, AK 99504 Ph: (907) 337-6179 * Fax: (907) 338-3246 * Website: akwwc.com 4. TOPOGRAPIIY: As can be seen on the attached topography site plan, the average topography of this property is a 5 to 10 percent running from approximately southeast to northwest. There is a vertical cutbank (5.7' drop) running along Birch Road; approximately 3 feet outside the east lot line. The slope that will occur between the invert of drainpipe in the proposed trench to the toe of the cutbank will be less than 25%. There is no concern associated with this separation distance. I am unaware of any adverse impacts this installation would have on adjacent wells or septic systems. If you have any questions, please contact us at 337-6179. Thank you for your assistance.

The data is organized in this report as follows: Test Pit Location Sketch Test Pit Log Standard Explanatory Data Data Not on Log Figure 1 Sheet 1 Sheets 2 to 4 Sheet 5 The test pit was dug by Dyess & Ziegler using a backhoe, on the 9th of May 1975. The test pit was logged and sampled by Mr. Peter Herstek, / technician of our staff. The testing and report by Alaska Testlab. The soils found in this study are predominantly frost susceptible sand silt gravel mixtures with silt prevailing. The material encountered from 2.0' to 5.0' was a non-frost susceptible sand. No free water level was observed in the test pit, and only 0.5' of frost (seasonal) was observed. The Greater Anchorage Area Borough has established the amount of seepage area per bedroom required for a particular seepage pit based On the unified classification of the soil. We understand this criteria to be as follows: Dr. Robert Brodie May 14, 1975 Page 2 Unified Soils Classification GW-GP GM SW SP SM ML CL-CH Seepage Area Required 85 square feet/bedroom 225 square feet/bedroom 125 square feet/bedroom 150 square feet/bedroom 250 square feet/bedroom . 275 square feet/bedroom 350 square feet/bedroom Soils with a seepage area value of greater than 250 square feet per bedroom are generally considered not sufficiently permeable to accept effluent. Additionally, the bottom of any seepage pit is required to be 4 feet above the free water level. The unified soils classification of each soil type encountered and the free water level (if any) observed at the time of exploration are contained on the test pit log, should proportioning a specific seepage pit in the area defined by · the test pit be required. If there should be any questions on the above, please contact our office. Very truly yours, ALASKA TESTLAB Lab.

If the tog includes soils samples, those samples receive an independent textural classification in the laboratory to verify the field examination. The logs often include the following items: Depth Interval - usually shown to 0.1 foot. within that zone no significant change in soil type was observed through drill action, direct bbservation or sampling. Frost Classification -- NFS, FI, F2, F3, F4, see "Soil Classification Chart" Texture of Soil - An engineering classification of the soils by particle size and proportion, see "Soil Classification Chart", note the proportions are approximate and modifications to the soil group due to stratification, inclusions and changes in properties are included. Moisture Content -- this is a qualitative measure: dr5,, no or little apparent surface moisture, damp, moisture forms portion of color, less than plastic limit, wet, no free water, often soft, if cohesive soil. saturated, free water may be squeezed out, ifa free draining soil; dilatent at natural moisture content, if a non-plastic silt or fine sand. (The moisture content is further defined by reference to PI. LW, NP, M% or dilatency.} Density - refers to more-ordess non-cohesive soils, such as sand gravel mixtures With or without a fine fraction, derived from drilling action and/or sample data; usually described as: very loose, loose, medium dense, very dense. General intent is to portray earthwork characteristics. Stiffness - refers to more-or-less cohesive soils and fine grained silts of the clay-silt groups. Derived from drill a:ction and/or sample data. Very soft, soft, stiff, very stiff and hard are commonly used terms. Particle size - The largest particle recovered by the split spoon is 1-3/8", Shelby tube 3", auger flights (minute-man! 2", Auger flights (B-S0 hollow stem} 6"-8". Larger particles are described indirectly by action of the drilling and are referred to as cobbles, 3" to 8", or boulders 8"+. Therefore when reviewing tlie gradation sheets, it' any, the description on the hole log must be considered for an indication of larger particles. Unified Soil Classification - This is a two letter code. See Unified Classification sheet for further definition. In some cases AASHO and/or FAA soil classifications may be shown as well as the unified. Atterberg Limits - useful for fine grained and other plastic soils. PI; natttral moisture content believed to be less than plastic limit PI+; natural moisture content believed to be between plastic and liquid limits Lw+; natural moisture content believed to be greater than liquid limit NP; non-plastic, useful as a modifying description of some silty ~-.[t erials. Dilatency - is the ability of water to migrate to the surface of a saturated or nearly saturated soil sample when vibrated or jolted - used as an aid to deter~nine il' a £ine grained soil is a slightly or non-plastic silt or a volcanic ash. Rock flour - finely ground soil that is not plastic but otherwise appears similar to a clayey silt. Organic Content -- usually described as Peat. PT, sometimes includes discrete particles such as wood, coal, etc. as a modifier to an inorganic soil. Quantity described as; trace, 9r an estimate of volume, or, in case of all organic, - as Peat. This may include tundra, muskeg and bog material. ~uck - a modifier used to describe very soft, semi-organic deposits usually occuring below a peat deposit. Amorphus peat - organic particles nearly or fully disintegrated. Fibrous Peat - organic particles more-or4ess intact. Bottom of Testhole - includes last sample interval. Frost Line -- seasonal frost depth as described by drilling action and/or samples at the time of drilling. Frozen Ground - other than frost line, described by samples, usually includes description of ice content, often will include modified Unit~ied Classification for frozen soils - this is a special case related to permafrost studies. Free Water Level -- The free water level noted during drilling. This is not necessarily the static water table at the time of drilling or at other seasons. Static water table determination in other than very permeable soils requires observation wells or piezometer installations, used only iu special cases. Blow/6" - The number of blows of a 140 weight free falling 36" to advance a 2" split spoon 6": the nmnber of blows for a 12" advance is, by definition, the standard penetration. M% - natural moisture content of the soil sample, usually not performed on clean sands or gravels below the water table. Type of Sample - S__P, refers to 2" split spoon driven into the soil by 140 pound weight, a disturbed sample, _S, thin wall tube, "Shelby" used to obtain undisturbed samples of fine grained soil, C,, "grab" disturbed sample from auger flights or wall of trench, C.g_, cut sample, undisturbed sample from wall of trench. Dry Strength - a useful indicator of a soil's clayey fraction, N=None, L=Low, M=Medium, H=High Group - The samples are placed into apparently similar groups based on color and texture and arc arbitrarily assigned a group letter. Further disturbed tests including Atterberg Limits. grain size, moisture-density relationship, etc. may be performed on thc group attd arc assumed to reflect the geucral distrubcd characteristics of the soils assigned to thc group. This is ,tn important phase of the soil analysis and is used to standardize the various qualitative determinations and to rednce the number of quautitative tests necessary to describe the soil mass.
